Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. However, the spirit of the present invention is not limited to the presented embodiment, and those skilled in the art who understand the spirit of the present invention may add, change, delete, etc. other elements within the scope of the same spirit, through addition, change, deletion, etc. Other embodiments included within the scope of the invention may be easily suggested, but this will also be included within the scope of the invention.

In addition, components having the same function within the scope of the same idea shown in the drawings of each embodiment will be described using the same reference numerals.

1 is a schematic perspective view of an engraving-type printing method using a digital machine according to an embodiment of the present invention, and FIG. 2 is a flowchart of the engraving-type printing method using a digital machine according to an embodiment of the present invention.

1 and 2 , the engraving printing method using a digital machine according to an embodiment of the present invention includes a data forming step (S100), which is a step of forming original data through high-resolution scan, and converting the original data to a predetermined value. Set a setting value based on the division division step (S200), which is a step of dividing the division into divisions, the data analysis step (S300) which is a step of color-separating the divided original image data to analyze the color and height for each division, and the analyzed data Thus, it may include a printing step (S400) of printing the imitation.

In addition, the printing method may further include a similarity determination step (S500), which is a step of comparing the printed simulation data with the original image data and determining that they are similar when a predetermined condition is satisfied.

In addition, the method may further include a setting value calculating step (S600) of calculating a suitable setting value that satisfies the predetermined condition.

The data forming step ( S100 ) may include a scanning step of forming raw data of an original image, and a preprocessing step of forming pre-processed original data by preprocessing the raw data.

In the scanning step, original image data may be formed through high-resolution scanning.

For example, the high-resolution scan may be performed by a camera.

In addition, the high-resolution scan may be performed by a 3D scanner.

Accordingly, raw data including height data and color data of the original image may be obtained.

Here, the 3D scanner refers to a scanner capable of measuring shape, curvature, roughness, etc. in addition to image information, and can be broadly divided into two types: a contact type and a non-contact type. A contact-type 3D scanner is a method of measuring by directly touching an object with a probe called a transducer. CMM (Coordinate Measuring Machine) is a representative method, and it has excellent accuracy as this method has been used for a long time in most manufacturing industries. However, the measurement speed is slow compared to other scanning methods, and since it has to contact the surface of the object, it may cause deformation or damage to the object, and thus cannot be used in the present invention. The core technology of the non-contact 3D scanner is to irradiate light (usually a laser) on the surface of an object, called a third-order recognition finder (Range Finder or Laser Range Finder), measure the return time of the light, and measure the distance between the object and the origin of measurement. is a technique to save

In addition, in the pre-processing step, the raw data of the original image formed through the high-resolution scan may be stored through a computing device, and pre-processed to form the pre-processed original data.

For example, the pre-processing may be data processing so that raw data of an original image formed through the high-resolution scan can be divided into predetermined sections.

The computing device referred to in the present invention may refer to a device capable of processing information processing operations. For example, the computing device may include a desktop computer, a laptop computer, a smart phone, a personal digital assistant (PDA), a portable multimedia player (PMP), a mobile terminal including a portable terminal, and/or a smart TV.

In addition, software for pre-processing raw data may be installed in the computing device.

For example, the pre-processing may be to create an image file having a predetermined size.

In addition, the pre-processing may be to convert 3D data into 2D data.

In addition, the pre-processing may be to data the height of the original image measured by the 3D scanner.

However, the present invention is not limited thereto, and the pretreatment may be variously modified at a level apparent to those skilled in the art.

3 is an exemplary view for explaining a engraving-type printing method using a digital machine according to an embodiment of the present invention.

1 to 3 , the division dividing step ( S200 ) of the engraving-type printing method using a digital machine according to an embodiment of the present invention may be a step of dividing the original image data into predetermined divisions.

The partitioning step ( S200 ) may be performed by a computing device.

Also, in the computing device, software for partitioning and dividing the original image data may be installed.

For example, in the partitioning step ( S200 ), the original image data received in the data forming step ( S100 ) may be divided into predetermined partitions.

For example, the predetermined partition may be a square.

For example, the predetermined division may be 1 pixel x 1 pixel unit.

However, the present invention is not limited thereto, and the predetermined partition may be variously modified at a level apparent to those skilled in the art.

The original image data partitioned into the predetermined partitions may be expressed in a matrix.

For example, in the case of original data located in 7th row and 2nd column, it may be expressed as (R7, C2).

For this reason, it is possible to easily match the partitioned original data and the partitioned simulated data.

In the data analysis step ( S300 ), color and height may be analyzed for each segment by color-separating the segmented original image data.

The data analysis step (S300) includes a division enlargement step, which is a step of expanding the divided original picture data, a color separation step, a step of color-separating the enlarged original picture data to extract the four primary colors 410 and spot colors 420, extraction A difference value is calculated by comparing the height corresponding to the amount of use with the height of the won measured in the amount calculation step and the data forming step (S100), which is a step of calculating the amount used for realizing the used color and the height corresponding to the amount used. It may be provided with a difference value calculating step.

Also, the data analysis step ( S300 ) may be performed by a computing device.

In addition, the computing device may be installed with software capable of enlarging the original image data, color separation, and calculating color and height data.

In the division enlargement step, the original image data may be enlarged by a predetermined multiple.

Due to this, it is possible to classify and check the overlapping colors, which are difficult to confirm with the naked eye, by color through the computing device.

For example, the predetermined multiple may be 20 times.

However, the present invention is not limited thereto, and the predetermined multiple may be variously modified at a level obvious to those skilled in the art.

In the color separation step, the original image data may be extracted and classified into blue (Cyan), red (Magenta), yellow (Yellow), and black (Black) colors, respectively.

Also, in the color separation step, the original image data may be extracted and classified into a blue spot color, a red spot color, a yellow spot color, and an ink spot color, respectively.

However, the present invention is not limited thereto, and the colors classified in the color separation step may be variously modified at a level obvious to those skilled in the art.

The amount calculation step may calculate a usage amount for realizing the color extracted in the color separation step and a height corresponding to the usage amount.

For example, in order to implement the color of the original data whose matrix values of the partitioned original data are (R7, C2), 75% of the red (M) type color is used, and the height corresponding to 75% may be 1.2mm. .

In addition, 33% of the yellow (Y) type color is used for (R7, C2), and the height corresponding to 33% may be 0.5 mm.

For this reason, the section corresponding to the position of (R7, C2) is a color in which 75% of red (M) and 33% of yellow (Y) are overlapped, and the height of the section may be 1.7 mm.

Here, the percentage (%) for each color type is a value obtained by dividing the steps from 0 to 255 according to the size of the dots and the density of the dots, and digitizing the maximum value of 255 as a percentage by corresponding to 100%.

In the step of calculating the difference value, the difference value may be calculated by comparing the height of the section with the height of the original currency measured in the data forming step ( S100 ).

For example, in the step of calculating the difference value, when the height of the original image measured in the data forming step S100 is 2.8 mm and the height of the section is 1.7 mm, the difference value of 1.1 mm may be calculated.

Accordingly, it is possible to obtain a value that can be corrected so that the height according to the amount of ink used for realizing the color is similar to the height of the actual original picture.

In addition, the height data corresponding to the usage may be data formed through a prior experiment and inputted to the software in advance.

4 is an exemplary view for explaining a engraving-type printing method using a digital machine according to an embodiment of the present invention.

1 to 4, the printing step (S400) of the engraving printing method using a digital machine according to an embodiment of the present invention sets a setting value based on the data analyzed in the data analysis step (S300). You can print imitations.

In addition, the printing step (S400) is a four primary color printing step (S410), which is a step of printing the four primary colors 410 consisting of blue (Cyan), red (Magenta), yellow (Yellow), and black (Black), the 4 A spot color printing step (S420), which is a step of printing using a spot color (420), which is a color other than the four primary colors (410), may be provided on the part where the primary color printing step (S410) has been performed.

In addition, the printing step (S400) further includes a height printing step (S430), which is a step of printing using the ink 430 for height adjustment on the printing paper, and the 4 primary color printing step (S410) is the height printing step ( The four primary colors 410 may be printed on the portion where S430) has been performed.

In addition, the setting value may be a value including the amount of ink used, the order in which the ink is used, the ejection direction of the ink, and the drying time of the ink.

For example, in the printing step (S400), the printing order of the four primary colors 410 in the printing step (S410) of the four primary colors may be changed according to the setting value.

Accordingly, a slight color difference may occur according to the printing order of the four primary colors 410 .

Specifically, type B printed in the order of yellow (Y), red (M) and blue (C) has a blue (C) color than type A printed in order of blue (C), red (M) and yellow (Y). This can be expressed more subtly.

Also, in the printing step (S400), the printing order of the spot color 420 in the spot color printing step (S420) may be changed according to the setting value.

However, the present invention is not limited thereto, and the printing order of the four primary colors 410 and the spot colors 420 may be variously modified at a level apparent to those skilled in the art.

In addition, the printing step (S400) may be printed in the order of the height printing step (S430), the four primary colors printing step (S410), and the spot color printing step (S420) according to the setting value.

However, the present invention is not limited thereto, and the order in which the ink is used may be variously modified at a level obvious to those skilled in the art.

In addition, in the printing step ( S400 ), the ejection direction of the ink may be changed according to the setting value.

For example, in the printing step ( S400 ), the ink may be ejected while proceeding only in one direction from the bottom to the top based on the original drawing.

For this reason, the replica printed in only one direction is displayed above the human eye, and when viewing the work from the top down, it is printed in only one direction, saving ink usage, and you can feel the color similar to the original painting. have.

In addition, in the printing step (S400), the ink may be ejected while proceeding in four directions, up, down, left, and right based on the original image.

Due to this, it is possible to implement the same quality in all four directions regardless of the viewing position.

Also, as an example, in the printing step ( S400 ), the ink may be ejected in a state where the ink is ejected in a stopped state for a predetermined time at the position where the ink is ejected.

For example, the predetermined time may be a time during which the ink may not be affected by the ejection movement due to the law of inertia.

Due to this, it is possible to implement the silk screen technique, which is a technique for printing while ink leaks through fine holes in the silk.

However, the present invention is not limited thereto, and the ejection direction of the ink may be variously modified at a level obvious to those skilled in the art.

In addition, in the printing step ( S400 ), the drying time of the ink may be adjusted according to the setting value.

For example, the drying time of the ink may be a time after the ink is ejected.

For example, the drying time of the ink may be 1 second after the ink is ejected.

Specifically, since ink is a fluid, when a large amount of ink is jetted, the ink height is initially formed high, but the ink is spread around by gravity, so that the ink height may be lowered.

For this reason, when the ink height is formed high, it can be dried immediately and hardened while the ink height is formed high.

However, it is not limited thereto, and the drying time of the ink may be variously modified at a level obvious to those skilled in the art.

The step of printing the four primary colors ( S410 ) may be a step of printing the four primary colors 410 .

For example, the four primary colors 410 may be blue (Cyan), red (Magenta), yellow (Yellow), and black (Black).

Also, the printing order of the four primary colors 410 may be determined by the setting value.

However, the present invention is not limited thereto, and the ink used in the four primary color printing step ( S410 ) can be variously modified at a level obvious to those skilled in the art.

The spot color printing step ( S420 ) may be a step of printing a spot color 420 that is a color other than the four primary colors 410 .

For example, the spot color 420 may be a blue spot color, a red spot color, a yellow spot color, and an ink spot color.

Also, the printing order of the spot color 420 may be determined by the setting value.

In addition, by using the spot color 420 , the color and texture of the original picture can be enriched.

However, the present invention is not limited thereto, and the spot color 420 ink used in the spot color printing step S420 can be variously modified at a level that is obvious to those skilled in the art.

For example, the spot color may include a silver spot color and a gold spot color.

In addition, the spot color printing step (S420) may be printed overlaid on the portion printed in the four primary color printing step (S410).

In addition, the spot color printing step (S420) may be printed on a portion not printed in the four primary colors printing step (S410) to supplement the four primary color printing step (S410).

Specifically, the four primary color printing step ( S410 ) may be printed by varying the size of dots and density of dots on the printing paper.

In this case, dots are formed by the ink ejecting device performing the four primary color printing step ( S410 ), and a blank space may be generated between the dots.

For this reason, in the spot color printing step (S420), the spot color 420 is printed overlaid on the dots formed by the four primary color printing step (S410), or the spot color 420 is printed in the blank space between the dots. The primary color printing step ( S410 ) may be supplemented.

In the height printing step (S430), a height similar to the original painting can be formed by adjusting the amount of ink 430 for height adjustment to compensate for the height formed by the four primary color 410 ink and the spot color 420 ink. have.

For example, the ink 430 for adjusting the height may be an ink that does not affect the color of the printed imitation.

For example, the ink 430 for adjusting the height may be an opaque white ink.

However, the present invention is not limited thereto, and the ink 430 for adjusting the height can be variously modified at a level that is obvious to those skilled in the art.

In addition, the height printing step (S430) may be performed first before the four primary colors printing step (S410) and the spot color printing step (S420) are performed.

For example, through the data analysis step (S300), the height to be formed by the four primary color printing step (S410) and the spot color printing step (S420) is calculated, and the height is printed by the calculated difference value by comparing the height of the original picture In step S430, the height adjustment ink 430 may be sprayed to correct the height to be similar to that of the original image.

Among the printing steps (S400), it may be preferable that the height printing step (S430) is performed first, but the present invention is not limited thereto, and various modifications are possible at a level obvious to those skilled in the art.

In addition, the printing step ( S400 ) may further include an ink drying step, which is a step of drying the printed ink.

As an example, a UV-ultraviolet lamp may be used to dry the printed ink.

Due to this, the printed ink can be dried instantaneously.

However, the present invention is not limited thereto, and the ink drying step may be variously modified at a level obvious to those skilled in the art.

In the engraving printing method using a digital machine according to an embodiment of the present invention, the similarity determination step (S500), which is a step of determining similarity when a predetermined condition is satisfied by comparing the printed simulation data with the original image data, may include more.

The similarity determination step (S500) is a simulation data forming step of forming the data of the simulation, a step of dividing the simulated data into the same partition as the original image, dividing the simulation partition, and analyzing the divided simulation data. It may include a simulation similarity determination step, which is a step of determining the similarity by comparing the human simulation data analysis step and the original image data and the simulated data.

The simulation data formation step, the simulation partition division step and the simulation data analysis step correspond to the data formation step (S100), the partition division step (S200) and the data analysis step (S300). can proceed.

The simulation similarity determination step may be a step of determining similarity when a predetermined condition is satisfied.

For example, the predetermined condition may be a condition that a matching division is equal to or greater than a predetermined value by comparing the color or height of the simulated data for each division and the original image data for each division.

In addition, the predetermined value may be a condition that the matching section is 90% or more.

However, the present invention is not limited thereto, and the predetermined value may be variously modified at a level apparent to those skilled in the art.

Also, the predetermined condition may be a condition that satisfies both the first predetermined condition and the second predetermined condition.

For example, the first predetermined condition may be a condition that a matching section is equal to or greater than a predetermined value by comparing the color or height of the simulated data for each section and the original image data for each section.

In addition, the second predetermined condition may be a condition that the number of inconsistent divisions located within a predetermined radius based on each division is less than or equal to a predetermined percentage.

For example, the predetermined radius may be in units of 10 pixels x 10 pixels.

In this case, the predetermined percentage may be 20% or less.

For this reason, the second predetermined condition can confirm the density of the non-matching section, thereby further increasing the degree of similarity between the original image and the simulated image.

However, the present invention is not limited thereto, and the predetermined radius and the predetermined percentage may be variously modified at a level apparent to those skilled in the art.

In addition, the meaning of 'color matching' in the predetermined condition is that when the percentage (%) for each color type in the same partition location is compared, the value of the percentage (%) for each color type is within a predetermined error range. value can mean

Specifically, when the value of the predetermined error range is 1%, the values of (R7, C2) of the original image are 75% of red (M) and 33% of yellow (Y), and (R7, C2) of the simulated image. If the values of red (M) are 74% and yellow (Y) 32%, the division of (R7, C2) can be determined as color matching.

However, the present invention is not limited thereto, and the meaning of 'color matching' and the value of the predetermined error range may be variously modified at a level obvious to those skilled in the art.

For example, the meaning of 'color matching' may be that the sum of color error range values for each type is within 1%.

Specifically, the value of (R7, C2) of the original picture is red (M) 75%, yellow (Y) 33%, and the value of (R7, C2) of the simulated picture is red (M) 74%, yellow ( If Y) is 32%, since the sum of the color error range values for each type is 2%, the division of (R7, C2) may be determined as a color mismatch.

In addition, if the predetermined condition is satisfied, printing may be terminated, and if the predetermined condition is not satisfied, the setting value may be changed and printing may be performed again.

In addition, when the replica printed again by changing the setting value does not satisfy the predetermined condition, it may be printed with another setting value changed.

Due to this, a reproduction similar to the original picture in which the color and texture of the original picture are abundantly expressed can be obtained.

In addition, the number of times of reprinting because the predetermined condition is not satisfied may be limited to a maximum of 5 times.

However, it is not limited thereto, and the number of re-printing may be variously modified at a level obvious to those skilled in the art.

The engraving printing method using a digital machine according to an embodiment of the present invention may further include a setting value calculating step (S600), which is a step of calculating an appropriate setting value that satisfies the predetermined condition.

The setting value calculation step (S600) is to calculate a setting value calculation model through deep learning using the setting value for the past print, the original image data, and the simulated data, and an appropriate setting value based on the setting value calculation model may be a step of calculating

In addition, the setting value calculation model compares the data for each section of the past print that satisfies the predetermined condition with the data for each section of the original image data that does not satisfy the predetermined condition, and when the data for each section of the two objects match It may be a model in which a setting value of is extracted and the setting value is learned when a result printed according to the setting value satisfies a predetermined condition.

In this case, the deep learning may be a Long-Short Term Memory (LSTM) model.

Specifically, the deep learning uses an artificial neural network (ANN) that mimics the form in which neurons, which are neurons of the human brain, are connected, and includes a plurality of hidden layers.

In addition, the deep learning typically includes a Convolution Neural Network (CNN) and a Recurrent Neural Network (RNN), and the Long Short Term Memory networks (LSTM) model is a type of Recurrent Neural Network (RNN), and past data is structure that can affect

For this reason, the setting value predicted using the deep-learned setting value calculation model and the data of the simulation printed according to the setting value become deep learning data used for deep learning of the setting value calculation model once again. The predicted setting value is calculated, and the accuracy of the prediction is increased.

However, the present invention is not limited thereto, and the deep learning can be variously modified at a level obvious to those skilled in the art in addition to the LSTM (Long-Short Term Memory) model.

In addition, the setting value calculation step (S600) may be performed by the computing device.

In addition, the setting value calculation step (S600) may obtain external information to be used for deep learning learning from an external server.

For example, the external server may be a server having information about the artist, the technique of the original painting, and data about the artist's other works.

In addition, the external information may be information including information on the artist of the original picture, a technique used for the original picture, and information on the artist's other works.

However, the present invention is not limited thereto, and the external server and external data may be variously modified at a level obvious to those skilled in the art.

Hereinafter, a detailed description of the engraving-type printing system using a digital machine may be omitted to the extent that it overlaps with the contents described above in the engraving-type printing method using a digital machine.

A data analysis module and analysis for performing a data analysis step (S300), which is a step of dividing a partitioning module for performing a partitioning step (S200), a step of analyzing the color and height for each partition by color-separating the partitioned original image data It may include a printing module that performs a printing step (S400), which is a step of printing a simulation by setting a setting value based on the obtained data.
